| 摘要 |
The invention is concerned with a pressure-sensitive, electrically conductive composite sheet which enables a free selection of the pressure sensitivity, and which exhibits a large change in resistance upon compression. The sheet comprises an electrically conductive elastomer sheet obtained by blending an elastic high-molecular material with electrically conductive particles, and forming a dot pattern over at least one surface of the electrically conductive elastomer sheet, the dot pattern being composed of an electrically insulating material and having a form that satisfies the following requirements: -Diameter of dots R = 0.3 to 1.5 mm -Thickness of dots d = 0.01 to 0.10 mm -Distance between centers l = (0.1 to 3.0) + R -of neighboring dots - |
